Exam 5: Temperature and Heat

specific heat capacity of ice = 2,000 J/kg-°C latent heat of fusion of water = 334,000 J/kg specific heat capacity of water = 4,000 J/kg-°C -As the ice is melting,the temperature of the ice-water mixture rises by 10°C.

You hold one end of a solid rod in a fire,and the other end becomes hot.This is an example of __________.

​Match each item with the correct statement below. -can be increased by doing work on a substance or by adding heat to it

As the air cools at night the relative humidity usually drops.

An object transfers heat when its temperature is lowered by contact with

A piston compresses a gas,while at the same time heat is lost to the surroundings.The temperature of the gas rises.This is governed by the second law of thermodynamics.

When droplets of condensation form on the outside of a glass of ice water,it must be that in the air right next to the glass

A material through which heat conducts slowly is called a __________.

When a substance is exposed to something that has a lower temperature,

The efficiency of a heat engine

Match each item with the correct statement below. -the maximum possible humidity

A wood stove in the corner of a cabin causes the entire cabin to become heated.This is an example of

The Eiffel tower in Paris is made primarily of iron,whose coefficient of linear expansion is about 10 × 10−⁶/°C.On a cold day when the temperature is −10°C the Eiffel tower is 300 meters tall.Its height on a hot day when the temperature is 40°C is 300.15 m.

The temperature of a gas can be increased by

A hot pizza contains heat.

​Match each item with the correct statement below. -the density of water vapor in the air

The latent heat of vaporization of water is roughly 10 times the latent heat of fusion of water.The amount of heat required to boil away 1 kg of water is __________ the amount of heat required to melt 1 kg of ice.

In the first law of thermodynamics,the work can be
